Softswitch Solution and Types Of Class 4 Switches Features and Advantages of Softswitch

The rise of VoIP has led to widespread use of softswitch solutions to serve as the intermediary in a telecom network comprising of standard PSTN and VoIP networks. Softswitches also serve to separate call functions from the transport layer. A softswitch can also function as a VoIP server and incorporate IP PBX call features. Softswitches are classified according to the functions they perform in the VoIP network.

Typically, telecom carriers and VoIP services make use of two different kinds of VoIP softswitches. One is class 4 softswitch and the other is class 5 softswitch. Class 5 softswitch works at the retail end of the VoIP network by connecting to the end user. Class 4 softswitch addresses the need of international bulk VoIP traffic from one telecom carrier to another.

Even in class 4 softswitch segment one can find two types of such switches. One is the local tandem switch or sector. This type of class 4 softswitch usually connects to class 5 softswitch to route traffic to local areas. Traffic from an exchange in one city originates in class 5 and tries to access a number in another city and, when it cannot, the class 4 tandem switch comes into play in the other city that, in turn, connects to the local class 5 softswitch and finds the number.

The other type of class 4 softswitch is the access tandem switch. This operates between bulk telecom carriers known as interexchange carriers. The local class 4 call travels across international networks to another telecom operator in another country and accesses the class 4 softswitch in that exchange. Class 4 softswitches can be configures to suit Competitive Local Exchange Carriers (CLECs), ITSPs, Incumbent Local Exchange Carriers (ILECs) and Multi-tenant environments in addition to bulk carriers.

Softswitches have changed the way telecom carriers operate. Open source based softswitches are software solutions and are highly affordable as well as scalable. There is no need to invest in hardware as traffic goes up. Softswitches do not just route calls; they also have other features such as billing and reporting. Then there are other features such as Do Not Disturb, call hold, call back, voice and video telephony, directory, voicemail, fax to mail, call blocking, call rejection, DID, extension dialing and intelligent call routing. Softswitches can route calls through predefined instructions and thereby lower cost of international calls. At the same time, the reporting and analytics as well as monitoring functions ensure that there is no call fraud and that no calls remain unbilled, thereby increasing revenues for carriers. Businesses that switch to VoIP enjoy benefits like cost reduction of calls and increased productivity besides other features like the ability to use services on IP PBX in house and on mobiles, a boon for mobile employees.


How Class 4 Softswitch Is Useful for VOIP Service Providers

This blog is in the continuation of the previous one- Analog of the two major VOIP solution- Class 4 Softswitch and Class 5 Softswitch wherein we discussed two different VOIP Softswitches in brief and their comparison. In this blog, we will discuss Class 4 Softswitch in detail.

Softswitches act as the key device that connects calls from one line to another, over different exchanges and transport areas, completely through the means of a software solution. Most of the calls are transmitted through electronic hardware but Softswitches route calls using VOIP servers. At present, telecommunication networks are leveraging the combination of the Softswitch and purpose-built hardware to make calls smooth without any interruption.

What is Class 4 Softswitch?

Class 4 Softswitch is a wholesale carrier that routes a substantially large volume of data between different exchanges and transport areas known as LATAs. It is completely different from the traditional hardware based call routing. The main qualities of Class 4 Softswitch are; track calls per second, average one time call routing, number of calls, protocol support and conversion.

Why is there a need for Class 4 SoftSwitch solution?

There were many barriers in the traditional telephony system, especially during long-distance calls. To dial an international call, we had to contact the telephone operator to transfer the call. This communication was expensive and sometimes interrupting, either the call used to not get connected or the disturbance in line broke the communication in the mid. The introduction of Class 4 Softswitch resolved the challenges making communication quick and easy like we never thought of. No extra calling cost. No extra hardware or software solution required for integration.

Analogy of Two Major VOIP Solutions: Class 4 Softswitch & Class 5 Softswitch

The introduction of VOIP has brought a revolution in the telecommunication industry. The major communication problems seemed to be solved and streamlined which was never thought of. Conferencing solutions introduced 3-way calling and sharing of content with a group of people located in separate places. IP PBX solved the biggest problem of internal communication by connecting IP address with the extension numbers. This eliminated the integration of extra hardware and cables. With Class 4 Softswitch and Class 5 Softswitch, trunk calls and long-distance calls became the things of the past.

In this blog, we will cover Softswitch, Class 5 Softswitch, Class 4 Softswitch and the analogy of the two. Class 4 and Class 5 Softswitch are a bit complex terms to understand So, here we are helping you in contemplating the two major terminologies of VOIP.

Shall we begin?


Softswitch is the convergence of the software and switchboards. In the early days of telecommunication, switchboards were used to route phone calls but now these calls are automated through Softswitch. Softswitch and switchboards work the same but today, these calls are automated and managed by VOIP servers.

Class 5 Softswitch

Class 5 Softswitch transmits a small volume of data. It is referred to as retail carrier because it manages calls of the immediate end-users within the city or town. One can associate normal telephone device with Class 5 Softswitch employing the IP connector. To connect international calls, Class 5 Softswitch passes traffic to Class 4 Softswitch travelling via different exchanges or carriers.

The key features of Class 5 Softswitch are:

  • Analog to digital conversion
  • IVR
  • Call Transfer
  • Call Forking
  • Call Holding
  • Call Back
  • Billing & Routing

Class 4 Softswitch

Class 4 Softswitch transmits a large volume of data especially international calls. It is referred to as wholesale carrier because it routes multiple calls traffic between different exchanges and other transport areas profoundly known as LATAs (local access and transport areas). Therefore, it is safe to say that Class 4 Softswitch routes the calls between various Class 5 Softswitch areas.

The key features of Class 4 Softswitch are:

  • UI support
  • Track of number of concurrent calls
  • Call authentication
  • Intelligent Call Routing
  • Secured Firewall

In simple words, Class 4 Softswitch is used for international calls whereas, Class 5 is used for local calls.

Take a look at a couple of examples to bring a clarity of Class 4 Softswitch and Class 5 Softswitch:

Example 1: A person calling from USA – Florida using IP phone to IP phone in USA-Ohio. This calling will be handled by a local VOIP service provider using Class 5 Softswitch because the call is made between two cities of the country USA.

Example 2: A person calling from South Africa using IP phone to IP phone in Ahmedabad. The first segment of the call will be transmitted to the local VOIP server where Class 5 Softswitch is installed. The second segment of the call will be transferred to Class 4 Softswitch from Class 5 Softswitch. The switching of calls can be done in two ways. First, if the VOIP service provider has both Class 5 Softswitch and Class 4 Softswitch installed on his server then the long-distance/ international calls can be easily switched from Class 5 to Class 4 Softswitch. Second, if the VOIP service provider has only Class 5 Softswitch installed then to transmit international calls, he has to analog calls to another server where Class 5 Softswitch can easily transmit the call to Class 4 Softswitch.

One important thing to note here is:

There is no curtailment for using Class 4 Softswitch and Class 5 Softswitch; The calls can be made from IP phone to IP phone or from IP phone to PSTN (Public service transfer) aka telephone or mobile phones.

Video Conferencing Technology for Distributed Workers is Getting Better and Better

Video conferencing is nothing new. The technology has been around for decades and it has been evolving continuously over the years. On the one hand there is the traditional desk top specialist video conferencing solution with appropriate hardware and software that necessitated everyone in an organization to gather into a room to carry on a teleconference. Today, it is different as one can use smartphones to carry out a video conference from anywhere, at any time, using appropriate software.

Changing trends, evolving technologies

The way people work and interact has changed. It is not necessary for a company to have employees working in its office. It is about distributed workforce these days. Whether it is a single company with just one office or a multinational, they all have employees in different locations. Communications and interactions have become easier, speedy and better with the implementation of WebRTC into video conferencing solution development . Anyone using a computer, a laptop or a smartphone can simply use the browser to start and take part in a one to one or multi-person interaction. Viewing another person and carrying on a chat is good no doubt but there are limitations. This is where future technologies make it even better.

AR and VR revolutionize video conferencing

The future is AR and VR rolled into the video conferencing solution. Donning a headset and carrying on a conversation is a quite difference experience. One can turn one’s head this way or that and view the person with whom one is chatting. It is possible to display documents and presentations when AR/VR becomes part of the conferencing solution development. For workers spread out over various geographic locations this is a great way to interact. It is as if one is there in person. At the same time, improved codecs and implementations reduce bandwidth load while assuring seamless videos without breaks or jitters that were once the bane of video calls.

Ease of use, lots of features, Unified communications

Video conferencing that blends in the best of audio conferencing features such as authentication, participant name recording, DTMF, recording, scheduling, polling, notifications and rollcall features, to name just a few, make it even better at interactions between distributed workforces. The right video conferencing software includes all these features besides being scalable and user-friendly, a unified communication system. Distributed workers need not bother about complicated setup—this is handled in the backend. All they need to concern themselves with is to use their smartphone for video calls with head office personnel or with other workers in any part of the world.

Benefits of Artificial Intelligence When Integrated Into Contact Center Solutions

VoIP transformed the contact center industry with a host of features not available in traditional telephony systems. AI (Artificial intelligence) is expected to have the same impact on contact centers and their operations.

Automating operations

Normal contact center solution involves interaction between a call agent and the customer. Call center solution development that incorporates artificial intelligence has the potential to let the system have virtual customer assistants that can handle most routine tasks. AI can analyze past queries of a caller and predict the query he will put forward and then divert the call to a human agent if desired. Time is no longer a constraint as chatbots can handle callers from any time zone or location and even translate languages. Customers do not have to wait interminably and press various keys that are usual in the IVR system. Big data allied with AI will help call centers perfect call center solutions that present agents with all data about a caller and address his query quickly and efficiently.

Track agent behavior

How agents respond and perform is also important for contact centers in order to assure customer satisfaction. Contact center solutions incorporate artificial intelligence to track behavior of agents. The same function can be used by the system to learn how to respond to various queries and the course of action. AI is becoming smarter with the ability to “sense” caller sentiment and take appropriate action for diverting the call to an agent at the right level for immediate resolution.

Intelligent Routing

Contact centers may also receive email requests for some service or the other in which case intelligent bots can assess the query and route it to a live agent.

Predictive analysis

Contact center agents often have the task of closing a sale or getting a commitment from a customer but may not be able to gauge the customer’s stand. In such cases artificial intelligence in call center solution development helps in predictive models based on emotions, speech patterns and behaviors. The system suggests to an agent whether it is worth pursuing the matter with a person to close a sale or to leave it.

Artificial intelligence works both ways. It can derive intelligence on caller behavior and mood and it can monitor call agent performance as well as assist him.

Importantly, AI can be incorporated into the contact center VoIP system and bring about changes in speed and operational efficiency by, for instance, doing away with or modifying IVR in a way that reduces wait time for callers and delivers speedy assistance. It is the future.

How Custom White Label VoIP Mobile Dialer Development Helps Service Providers Achieve Value Addition

Mobile devices have revolutionized telephony and VoIP has made international calling more affordable than ever. Individuals use mobile softphones available as apps that can be installed with ease on a variety of smartphones. Business users too have plenty of choices in off-the-rack softphone solutions with a host of business-friendly and relevant features. For service providers it is a different matter. Standard VoIP mobile dialers just won’t cut it.

Custom dialer application development is recommended for VoIP service providers. Ecosmob VoIP mobile dialer development and solutions packages are tailored to suit business needs of service providers with the intent to generate revenues, create branding and ensure loyalty.

A highly desirable feature for service providers intending to establish a strong brand presence and thus engender loyalty is white labeling service available from Ecosmob. White label means extreme customization of not only standard features intrinsic to VoIP mobile dialers but other equally important ones. These include theme and overall layout that are in consonance with the company’s branding. Language of choice is included in customized white label mobile dialer app development to make it appear as if the service provider has his own product, something that resonates strongly with customers.

Service providers need not opt for features they have no use for. Custom development of VoIP mobile dialer includes multiple SIP accounts support, phonebook integration, call statistics, call timers, call history, video and audio calls, redials, full support for all audio/video codecs and call hold/forward/retrieve/transfer. They pay only for features they need to start with and have options to upgrade. This reduces initial capital outlay.

Custom dialer application development means service providers can deploy branded white labeled dialers for Android, iOS, Blackberry and Windows OS according to their needs. Importantly, the app can be used by businesses besides service providers and ensure security of communications as well as uniformity and assured performance because everyone within the organization uses the same app. Further, customization and an easy to use control panel allows administrators to grant permissions as they see fit, something that may not be available in off the rack solutions. Service providers and businesses may need to integrate it with CRM or other backend solutions for accounting, reporting or analytic purposes in which case, again, opting for custom dialers is the way to go. Equally important is service and support that custom developers promptly offer for any modification or troubleshooting.

In the final analysis one may end up saving more by paying a little extra for custom dialers because the returns are so much more in tangible and intangible ways.

Importance of Multi Tenant Solutions for VoIP Domain

How Softphone works for VoIP

A Softphone (Software Telephone) is a software that can enable calling from the computer. The softphone enables the user to place calls as well as to receive them.

Depending upon the type of connection, we can integrate the softphone in the communication system for making calls using conventional PSTN (Public Switched Telephone Network) or via VoIP telephony. With VoIP Softphone, you can make calls with your desktop or laptop using a VoIP service. Skype, iChat, and GoogleTalk are some of the highly popular services that use the revolutionary VoIP technology.

How does Softphone work?

A Softphone’s interface acts in the same fashion as a physical phone’s interface; however, unlike a physical handset, the display is projected on the user’s screen. It works clearly by converting original telephone audio into the digital format that can be transmitted over the Internet. Also, it converts incoming digital signals from the Internet to standard telephone audio. Since it is an application, it also requires a microphone, loudspeaker, and headset for the voice communication.

Most softphone applications also include various features to give us increased value as compared to the traditional communication method. For example, many softphones feature a built-in instant messaging feature that enables you to send a text message rapidly without making a time-consuming phone call. Another great benefit that softphones offer is visual voicemail. It’s like treating your calls like an email browser. These features make Softphone a smart choice!

Benefits of Softphone :

  1. Cost-effective solutions: Softphones offer affordable call rates using the VoIP technology. Also, they don’t require conventional desk phones and saves the cost of wiring. This ultimately minimizes the investment and proves to be a cost-effective communication solution.
  2. Digital database: You need not bother maintaining a physical phone directory to call individuals. With the Softphone, you can easily call someone directly from the computer’s address book, only by clicking the number.
  3. Replace the traditional desk phones: Many mobile workers, office users and even individuals at home prefer softphones over the traditional desk phones as they are highly convenient. They don’t occupy space and offer wireless software solutions.
  4. Unified solution: These days, businesses are expanding, and you need to stay in touch with your business partners and customers. With a Softphone, you can keep your contacts updated, irrespective of your location and can access them from anywhere. You can also save more cost on the national and international roaming with the Softphone. Inbuilt features of softphone are speed dialing, teleconferencing, text, IM, video capabilities, call forwarding, call waiting, etc.

The features and functionality of each softphone will vary from one softphone provider to another. But, you can always ask to add more features with the customized Softphone solution. Softphones won’t compromise with the quality of communication, rather saves your time to manage database as well as prevent your staff from working on tedious and time-taking tasks. Softphones will be most advantageous in the contact center and help desk.

The PC is always on and the sole function of the agent is to speak, listen, enter and retrieve data. It keeps your customers and client content with the services and ensures round-the- clock connectivity.
